Which letter correctly identifies a process of the hydrologic cycle? This question is often asked in educational settings to test students’ understanding of the Earth’s most fundamental cycle. The hydrologic cycle, also known as the water cycle, is a continuous process through which water moves between the Earth’s surface and the atmosphere. It plays a crucial role in shaping our planet’s climate and supporting life. To answer this question, we need to explore the various stages of the hydrologic cycle and identify the letter that corresponds to the correct process.
The hydrologic cycle consists of several interconnected processes, including evaporation, condensation, precipitation, collection, and runoff. Let’s examine each of these stages to determine which letter represents the correct process.
A. Evaporation: This is the process by which water from oceans, lakes, rivers, and other bodies of water is converted into water vapor and rises into the atmosphere. It is the first step in the hydrologic cycle and is essential for the transport of water from the Earth’s surface to the atmosphere.
B. Condensation: This stage occurs when water vapor in the atmosphere cools and turns back into liquid water, forming clouds. Condensation is the second letter in the sequence and is a crucial step in the hydrologic cycle, as it leads to the formation of precipitation.
C. Precipitation: This is the process by which water droplets or ice crystals in the clouds fall to the Earth’s surface as rain, snow, sleet, or hail. Precipitation is the third letter in the sequence and is vital for replenishing water sources and supporting ecosystems.
D. Collection: This stage refers to the accumulation of precipitation in various water bodies, such as lakes, rivers, and oceans. Collection is the fourth letter in the sequence and is essential for maintaining the Earth’s water supply.
E. Runoff: This process occurs when excess water flows over the Earth’s surface, typically after heavy rainfall or snowmelt. Runoff is the fifth and final letter in the sequence and plays a significant role in replenishing groundwater and transporting nutrients and sediments.
Based on the stages described above, the correct answer to the question “Which letter correctly identifies a process of the hydrologic cycle?” is B. Condensation. This letter represents the second stage in the hydrologic cycle, where water vapor in the atmosphere cools and forms clouds, leading to the formation of precipitation. Understanding the various stages of the hydrologic cycle is crucial for appreciating the importance of water on our planet and the delicate balance it maintains.
